I need to generate a bipolar analog current source where I can control the amplitude, frequency, and pulse width.  Is there an example project that will help me get started.  I am open to using PSoC 1, 3, or 5.  Thanks.

 In PSoC3/5, you have ready made implementation of IDAC. You can use those IDACs to generate a bipolar current source by controlling the source/sink bit. I doubt that there is an example project available for IDAC but yes there is one for VDAC - A similar one can be used for IDAC as well. 

Using PSoC1, you can design a solution as shown in the figure attached. Opamp can be implemented using SCBLOCK by referring to the FAUX Opamp -
